Talmudic scholar. He began the study of the Talmud at Salonica about 1630, and was a fellow-student of David Conforte ("Ḳore ha-Dorot," ed. Cassel, 52b). He is probably not identical with the Isaac Cavellero who was a preacher at Venice in the second half of the seventeenth century, and whose sermons were published by his relative Judah ben Joseph Perez under the title "Naḥal Etan" in the "Peraḥ Lebanon" (Berlin 1712).

Italian scholar; son of Shem-Ṭob Cavallero; flourished at Venice at the end of the sixteenth and beginning of the seventeenth century. He was the author of "Orden de Oraciones" (Venice, prior to 1583), an edition of the prayer-book according to the ritual of the Spanish and Portuguese Jews, and containing the Hebrew text with a translation into the Spanish vernacular; a second edition, to which the "Declaracion de los Puntos" was appended, was published at Venice in 1622. The "Orden de-Oraciones" was placed upon the "Index Librorum Prohibitorum," edited by Caspar á Quiroga (p. 69b, Madrid, 1583).

Lived at Salonica about 1515; corresponded with Elijah Mizraḥi and with Tam (Jacob) ibn Yaḥya (Conforte, l.c. pp. 33a et seq). It was for him, or for a contemporary mathematician of the same name living at Salonica, that Ephraim Mizraḥi translated into Hebrew Georg Peurbach's "Theorica Planctarum" under the title "Ṭioriḳa ha-Niḳra' Mahalak ha-Kokabim."
